22 Inch GFF Capacitive Touch Panel USB For Industrial Electronic Equipment

The surface capacitive touch screen utilizes the ITO (Indium Tin Oxide) at the touch screen surface to achieve a change in electrical current upon contact with the human body. The change is registered by the sensors placed at the four corners and transmitted to the controller as an analog signal. The signal will then be processed by the controller before it is sent to the system as a digital signal to be displayed visually on the monitor.

22" capacitive touch screen panel

Advantages:

1. Highly transparent with a transmittance of 95%~99%
2. Tempered glass with a scratch hardness of 7H: the Vandal-Proof structure makes the product more suitable for systems in public places.
3. High sensitivity: the touch screen functions by sensing electrical currents from the human body and is capable of offering immediate response at the slightest touch (a response time within 16ms at a stress load of below 30g).
4. The extremely high transmittance (up to 99%) and 7H of scratch hardness, coupled with water and dust resistant surface design makes the product best suited for general public applications.
